"Let It Go", the epic single from the smash Disney film Frozen, has been memorably covered by Pentatonix. This a cappella setting inspired by that version dazzles with harmony, color and emotion for a spectacular choral showcase. Adapted from the Pentatonix cover of "Rather Be" by Clean Bandit, this is an awesome vocal showcase for pop and show groups from high school and up! Irresistible! "Save the World/Don't You Worry Child" has the vibrant a cappella sounds of Pentatonix, the accessible setting of the mash-up by Swedish House Mafia also has optional accompaniment, making this a fantastic showcase for high school pop and show choirs.
